Counters are available as experimental features on Scylla 1.7 and production ready on Scylla 2.0. To enable experimental features in Scylla, add the line experimental:true to scylla.yaml.

Counters are useful for any application where you need to increment a count, such as keeping track of:

the number of web page views on a website;

the number of apps/updates downloaded;

the number of clicks on an ad or pixel;

the number of points earned in a game;

A counter is a special data type (column) that only allows its value to be incremented, decremented, read or deleted. As a type, counters are a 64-bit signed integer. Updates to counters are atomic, making them perfect for counting.
